Abstract
The utility model discloses an intelligent variable-pressure water tank used for solar water heater. A flow switch is arranged on a water outlet pipe, a normally closed solenoid valve is arranged on a water inlet pipe, a normally opened solenoid valve is arranged on a circulation pipe of a water storage tank, the flow switch is connected with circuits of the normally closed solenoid valve and the normally opened solenoid valve, a water level switch is positioned at the upper part of the water storage tank, and the water level switch is connected with the circuit of the normally closed solenoid valve on the water inlet pipe. The intelligent variable-pressure water tank has long service life and good safety and reliability and ensures that the service life of an inner container of the water tank can be prolonged by 3 to 5 times.
Description
Technical field
The utility model relates to a kind of solar water heater, especially relates to a kind of intelligent pressure swing type water tank.
Background technology
The balcony wall-hanging solar water heater is gone through development in several years, it all is the totally-enclosed pressure-bearing type of water tank and heat collector, whenever water temperature rises 10 ℃, to produce 1 ㎏ pressure, like this, water tank and heat collector must can pressure-bearing 10 ㎏, and also to adorn safe pressure relief device at the water inlet place, can guarantee user's safe handling.And the inner water tank long-term work is at artesian condition, if enamel has crackle, at first from the cracks corrosion, makes inner water tank shortening in service life.
Summary of the invention
The purpose of this utility model is: at the problem and shortage that prior art exists, provide a kind of long service life, the safe and reliable intelligent pressure swing type water tank that is used for solar water heater.
The technical solution of the utility model is: comprise storage tank, water inlet pipe, outlet pipe, water inlet pipe is connected with the inner bag below of storage tank, outlet pipe is connected with the inner bag top of storage tank, storage tank has upper circular tube and following circulation pipe, flow switch is housed on the outlet pipe, normally closed solenoid valve is housed on the water inlet pipe, on the upper circular tube of storage tank normally open type magnetic valve is housed, flow switch is connected with the circuit of normally closed solenoid valve and normally open type magnetic valve, water level switch is equipped with on storage tank top, the circuit of the normally closed solenoid valve on water level switch and the water inlet pipe is connected normally open type magnetic valve, normally closed solenoid valve, flow switch and water level switch are by controller control system interlock.
The beneficial effects of the utility model are: during water, the steam of generation is discharged from normally open type magnetic valve in heat collector heating storage tank, and no matter water tank water temperature how many degree that rise can not produce pressure.When using hot water, open the hot water valve on the outlet pipe, hot water flows through from flow switch, flow switch is opened, and gives two magnetic valve voltages by controller, and two magnetic valves move simultaneously, the normally open type magnetic valve closure, normally closed solenoid valve is opened, and cold water begins to enter water tank from water inlet pipe, and hot water is ejected, for using hot water, at this moment, water tank becomes pressure, is tap water pressure.When using up hot water, close the hot water valve on the outlet pipe, outlet pipe water remains static, and flow switch cuts out, and cuts off power of electromagnetic valve, and normally open solenoid valve is in normally open, and normally closed solenoid valve is in normally off, becomes no setting-out case in the water tank again.When water storage tank water level reaches the water level switch position, water level switch is opened, normally closed solenoid valve is closed, in the time of can preventing that intake pressure is big, water outlet from normally open type magnetic valve.The utility model long service life, safe and reliable, can make improve 3-5 doubly the service life of inner water tank.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
From structural representation of the present utility model shown in Figure 1 as can be seen, comprise storage tank 1, water inlet pipe 9, outlet pipe 8, storage tank 1 has upper circular tube 4 and following circulation pipe 6, in order to connect solar thermal collector.Water inlet pipe 9 is connected with the inner bag below of storage tank 1, and outlet pipe 8 is connected with the inner bag top of storage tank 1, and cold water enters from water inlet pipe 9, and hot water is ejected from outlet pipe 8.Flow switch 7 is housed on outlet pipe 8, normally closed solenoid valve 10 is housed on water inlet pipe 9, on the upper circular tube 4 of storage tank normally open type magnetic valve 3 is housed, flow switch 7 is connected with the circuit of normally closed solenoid valve 10 with normally open type magnetic valve 3, during water, the steam of generation is discharged from this normally open type magnetic valve 3 in heat collector heating storage tank 1.On storage tank 1 top water level switch 2 is housed, the circuit of the normally closed solenoid valve 10 on water level switch 2 and the water inlet pipe 9 is connected, normally open type magnetic valve 3, normally closed solenoid valve 10, flow switch 7 and water level switch 2 are by the controller 5 control system interlocks that are arranged on the storage tank, reach passive state, realize automatic water-supply.When water storage tank water level reaches the position of water level switch 2, water level switch 2 is opened, normally closed solenoid valve 10 is closed, in the time of can preventing that intake pressure is big, water outlet from normally open type magnetic valve 3.
Operation principle of the present utility model is: when using hot water, open the hot water valve on the outlet pipe, hot water flows through from flow switch 7, and flow switch 7 is opened, and gives normally open type magnetic valve 3 and 10 2 magnetic valve voltages of normally closed solenoid valve, two magnetic valves move simultaneously, normally open type magnetic valve 3 closures, normally closed solenoid valve 10 is opened, and water tank is in artesian condition, cold water enters water tank, and hot water is ejected for using.When using up hot water, close the hot water valve on the outlet pipe, flow switch 7 cuts out, and cuts off power of electromagnetic valve, and normally open type magnetic valve 3 is in normally open, and normally closed solenoid valve 10 is in normally off, and water tank is in passive state, so recycles.When cistern water level reaches the position of water level switch 2, water level switch 2 is opened, normally closed solenoid valve 10 is closed.
